The Southeast Alaska Pacific Cod Fishery THE SOUTHEAST ALASKA PACIFIC COD FISHERY by Eric E. Coonradt Regional Information Report1 No. 1J02-10 Alaska Department of Fish and Game Division of Commercial Fisheries Juneau, Alaska May 2002 1 The Regional Information Report Series was established in 1987 to provide an information access system for all unpublished divisional reports. These reports frequently serve diverse ad hoc informational purposes or archive basic uninterpreted data. To accommodate timely reporting of recently collected information, reports in this series undergo only limited internal review and may contain preliminary data; this information may be subsequently finalized and published in the formal literature. Consequently, these reports should not be cited without prior approval of the author or the Commercial Fisheries Management and Development Division. FOREWORD This report provides species information on Pacific cod and the Pacific cod fishery. This report is designed to be used in conjunction with the 2002 Commercial Groundfish Fishing Regulations, active News Releases, and Emergency Orders. Inseason actions will supercede information provided in this document. AUTHOR Eric E. Coonradt is a fishery biologist with the groundfish project for the Alaska Department of Fish and Game, Division of Commercial Fisheries, 304 Lake Street, Room 103, Sitka, Alaska 99835-7563.

  • Conservation Prioritization of Prince of Wales Island
    CONSERVATION PRIORITIZATION OF PRINCE OF WALES ISLAND Identifying opportunities for private land conservation Prepared by the Southeast Alaska Land Trust With support from U.S. Fish and Wildlife Service Southeast Alaska Coastal Conservation Program February 2013 Conservation prioritization of Prince of Wales Island Conservation prioritization of Prince of Wales Island IDENTIFYING OPPORTUNITIES FOR PRIVATE LAND CONSERVATION INTRODUCTION The U.S. Fish and Wildlife Service (USFWS) awarded the Southeast Alaska Land Trust (SEAL Trust) a Coastal Grant in 2012. SEAL Trust requested this grant to fund a conservation priority analysis of private property on Prince of Wales Island. This report and an associated Geographic Information Systems (GIS) map are the products of that work. Driving SEAL Trust’s interest in conservation opportunities on Prince of Wales Island is its obligations as an in-lieu fee sponsor for Southeast Alaska, which makes it eligible to receive fees in-lieu of mitigation for wetland impacts. Under its instrument with the U.S. Army Corps of Engineers1, SEAL Trust must give priority to project sites within the same 8-digit Hydrologic Unit (HUC) as the permitted impacts. In the past 10 years, SEAL Trust has received a number of in-lieu fees from wetlands impacted by development on Prince of Wales Island, which, along with its outer islands, is the 8-digit HUC #19010103 (see Map 1). SEAL Trust has no conservation holdings or potential projects on Prince of Wales Island. In an attempt to achieve its conservation goals and compliance with the geographic elements of the Instrument, SEAL Trust wanted to take a strategic approach to exploring preservation possibilities in the Prince of Wales HUC.

  • Cole, Douglas. Sigismund Bacstrom's Northwest Coast Drawings and An
    Sigismund Bacstrom's Northwest Coast Drawings and an Account of his Curious Career DOUGLAS COLE Among the valuable collections of British pictures assembled by Mr. Paul Mellon is a remarkable series of "accurate and characteristic original Drawings and sketches" which visually chronicle "a late Voyage round the World in 1791, 92, 93, 94 and 95" by one "S. Bacstrom M.D. and Surgeon." Of the five dozen or so drawings and maps, twenty-nine relate to the northwest coast of America. Six pencil sketches of northwest coast subjects, in large part preliminary versions of the Mellon pictures, are in the Provincial Archives of British Columbia, while a finished watercolour of Nootka Sound is held by Parks Canada.1 Sigismund Bacstrom was not a professional artist. He probably had some training but most likely that which compliments a surgeon and scientist rather than an artist, His drawings are meticulous and precise, with great attention to detail and individuality. He was not concerned with the representative scene or the typical specimen. In his native portraits he does not tend to draw, as Cook's John Webber had done, "A Man of Nootka Sound" who would characterize all Nootka men; Bacstrom drew Hatzia, a Queen Charlotte Islands chief, and his wife and son as they sat before him on board the Three Brothers in Port Rose on Friday, 1 March 1793. The strong features of the three natives are neither flattered nor romanticized, and while the picture may not be "beautiful," it possesses a documentary value far surpassing the majority of eighteenth-century drawings of these New World natives.

  • HARBOR PORPOISE (Phocoena Phocoena): Southeast Alaska Stock
    NOAA-TM-AFSC-404 M.M. Muto et al. 2020 Revised 12/30/2019 HARBOR PORPOISE (Phocoena phocoena): Southeast Alaska Stock NOTE – December 2015: In areas outside of Alaska, studies of harbor porpoise distribution have indicated that stock structure is likely more fine-scaled than is reflected in the Alaska Stock Assessment Reports. No data are available to define stock structure for harbor porpoise on a finer scale in Alaska. However, based on comparisons with other regions, it is likely that several regional and sub-regional populations exist. Should new information on harbor porpoise stocks become available, the harbor porpoise Stock Assessment Reports will be updated. STOCK DEFINITION AND GEOGRAPHIC RANGE In the eastern North Pacific Ocean, harbor porpoise range from Point Barrow and offshore areas of the Chukchi Sea, along the Alaska coast, and down the west coast of North America to Point Conception, California (Gaskin 1984, Christman and Aerts 2015). Harbor porpoise primarily frequent the coastal waters of the Gulf of Alaska and Southeast Alaska (Dahlheim et al. 2000, 2009), typically occurring in waters less than 100 m deep; however, occasionally they occur in deeper waters (Hobbs and Waite 2010). Within the inland waters of Southeast Alaska, harbor porpoise distribution is clumped with greatest densities observed in the Glacier Bay/Icy Strait region and near Zarembo and Wrangell Islands and the adjacent waters of Sumner Strait (Dahlheim et al. 2009, 2015). The average density of harbor porpoise in Alaska appears to be less than that reported off the west coast of Figure 1. Approximate distribution of harbor porpoise in the continental U.S., although areas of high Alaska waters: crosshatched area - Southeast Alaska stock; densities do occur in Glacier Bay and the striped area - Gulf of Alaska stock; dark shaded area - Bering adjacent waters of Icy Strait, Yakutat Bay, the Sea stock.

  • Craig & Dixon Entrance Geophysics
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY An Interpretation of the Aeromagnetic and Gravity Data and Derivative Maps of the Craig and Dixon Entrance 1ox3o Quadrangles and the Western Edges of the Ketchikan and Prince Rupert Quadrangles, Southeastern Alaska By J.C. Wynn, R.P. Kucks, and D. J. Grybeck Digital Data Series 56 INTRODUCTION The U.S. Geological Survey (USGS) is required by the Alaska National Interest Lands Conservation Act (ANILCA, Public Law 96-487) to survey certain Federal lands to determine their mineral resource potential. As part of continuing studies designed to fulfill this responsibility, geochemical, geological and geophysical surveys of the Craig and Dixon Entrance (CDE) 1ox3o quadrangles in southeastern Alaska were undertaken by the USGS during the summers of 1983-85, 1989, and 1991. The geochemical data have been reported by Cathrall and others (1993) and Cathrall (1994). A simplified geologic map has been compiled especially for this report based largely on the work of Eberlein and others (1983) and Gehrels (1991, 1992). Brew (1996) also produced a compilation. This report presents available magnetic and gravity data and an interpretation thereof. GEOGRAPHIC AND GEOLOGIC SETTING OF THE CRAIG STUDY AREA The Craig study area comprises about 1,400 mi2 (3,600 km2) between latitude 54o40' and 56o N. and longitude 131o50' and 134o40' W. of the southeastern tip of the Alaskan Panhandle. The CDE quadrangles (fig. 1) are located west of Ketchikan and include all but the northern tip of Prince of Wales Island as well as outlying islands to the west from Dall Island in the south to Coronation Island in the northwest.

  • Background Information Regarding the Movements of Salmon Between Northern British Columbia and Southeast Alaska
    BACKGROUND INFORMATION REGARDING THE MOVEMENTS OF SALMON BETWEEN NORTHERN BRITISH COLUMBIA AND SOUTHEAST ALASKA Prepared by Fisheries Research Board of Canada Biological Station Nanairno, B. c. October, 1965 ,·_: CONFIDENTIAL BACKGROUND INFORMATION REGARDING THE MOVEMENTS OF SALMON BETWEEN NORTHERN BRITISH COLUMBIA AND SOUTHEAST ALASKA Prepared by Fisheries Research Board of Canada Biological Station, Nanaimo, B. c. FOREWORD Joint consideration by the United States and Canada of management problems caused by the movements of salmon between Northern British Columbia and Southeast Alaska began with the formation in 1959 of an international 11 Committee on problems of mutual concern related to the conservation and 11 management of salmon stocks in Southeast Alaska and Northern British Columbia • Background information on events leading up to the formation of this Committee and a brief outline of the Committee's activities from 1959 to the present are included in Appendix A of this report. Details of the Committee's findings are included in the Committee's most recent report (April 196~), copies of which have already been distributed. Since studies reported by the Committee were completed, a considerable amount of tagging has been done by Canadian and United States vessels, both on the high seas and coastal waters, as part of the INPFC research program. A brief account of the results of these tagging programs bearing on the problem of movements of salmon in the Northern British Columbia~Southeast Alaska area is given in Appendix B. In the Committee's report, information on the extent of interception was not available for all areas of concern. For this reason some of the estimates were characterized as being ''minimum".
